"A Moment Like This" is a song originally recorded by American singer, Kelly Clarkson, the winner of the first season of American Idol. It was released as her debut single along with "Before Your Love" on 17 September 2002 by RCA Records and charted at #1 on the U.S. Billboard Hot 100.
In December 2006, the song was recorded by Leona Lewis, the winner of series 3 of The X Factor. The single was rush-released on Wednesday, 20 December 2006 by Syco Records / Sony BMG Records. This is unusual as most new singles are released on a Monday to gain maximum sales for the UK Singles Chart the following Sunday. The late release of "A Moment Like This" was because Leona Lewis was only chosen as the artist on the night of Saturday, 16 December 2006, when the live final was transmitted. The song was available for download after she was announced winner of The UK X Factor. It was charted at #1 on the U.K. Singles Chart.
